DevNull 1.70 game start challenge

[gammer]

I am attempting to get True Destiny (a DevNull 1.70 game) started. I have been playing in another such game (Balance of Power), with no problems. I had no problems uploading my first turn, however, none of the other players have had any luck.

The message they have been receiving when they try to upload their first turn is:
"The Data files currently being used do not match the data files that were used when this game was started. Please check with your host to get the correct data files."

Unfortunately, as this is my first attempt at hosting a game (and one with a mod at that), I am at a loss as to what is happening or what to do to help the other players.

Can someone please help with this?
